Officers responded before 5 p.m. Monday to St. Charles Borromeo School, where a mother and her 4-year-old son had been struck by a vehicle driven by Zhang, the Sheriff's Office said.

Zhang was the estranged husband of the woman who was struck. Officials said they had recently separated.

Officials said the mother and child were taken to a hospital with minor injuries. Before he fled the scene, Zhang struck two other parked vehicles in the area. One of the people in those vehicles was also taken to a hospital with minor injuries.

During its investigation, the Sheriff's Office learned that the New Orleans Police Department responded to a suicide after 6 p.m. Monday on the Highrise.

Officials said Zhang was identified as the man who killed himself on the bridge. New Orleans police said his vehicle was found abandoned on the Highrise and his body was found underneath the interstate.

The Sheriff's Office said the vehicle was the same one that he used to hit his wife and her child.

Additional information about the case was not released.
